Letters Patent No. 84,792, dated Ijeccmber` 8, 1868.

The Schedule referred to in these Letters Patent and making part of the same.

To all nvhom. it ma/y concern:

Be it lknown that I, G. EfBosSELIER, of St. Louis, in the county of St. Louis, and State of Missouri, have invented a new and improved Compression-Cock; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable those skilled in the art to make and use the same, referencebeing had to the accompanying drawings,forming part of this specification.

This invention relates to improvements in cocks for discharging liquids or fluids; and

, Ascrew-tlnead is cut in the upper portion of theY shell, and the socket D has a corresponding screw- .thread ou its outside, which engages with that in the shell.

e is the valve-seat, and

f is the valve, which has an elastic face, g, secured by the screw h.

' The socket JA orcavity ofthe valve is square, or angular, or in any other convenient shape, so that it may be readily turned by revolving the stein, and the lower part of the stem is made to fit, as seen in the drawing.

vi is a collar on the stern,.which is rendered watertight by packing on both sides beneath thecap.

The cap screws on to the upper part of the shell, and thereby prevents all longitudinal motion in the stem C.

It will readily be seen that when the stem is turned or revolved by the handle lf, the valve will be raised or lowered, and that by screwing the cap on to the shell,

as in the drawing, the stem is kept securely in place,

while all breakage is prevented, by the elastic or rubber packing above and below the collar i.

I claim as new, and desire tc secure by Letters Patent- The valve D, having a screw-thread out upon its outer surface, and furnished with a smooth socket, J, in which the squared end cf the valve-stern O is fitted, said stem having a disk, i, bearing against the under sm'face of the packing placed in the recess of the cap B, and resting upon the lower packing-disk, secured to the shell A by the screw-cap, all arranged and op# erating as described, for the purpose specih'ed.

The above'specication of my invention signed by me, this 4th day of June, 1868.

' G. E. BOISSELIER.
